PLANlNG-MACHINE- SPECIFICATION forming art of Letters Patent No.623,938, dated April. 25, 1899.

Application filed March 21. 1896. Serial No. 584,268. tNo model.)

To all whom, it may concern:

Be it known that we, SOLOMON A. WOODS, of Brookline, county of Norfolk,and HOSEA R. TILLIsoN and CHARLES W. H. BLOOD, f Boston, county ofSuffolk, Stateof Massachusetts, have invented an ImprovementinPlaning-Machines, of which the following descri ption, in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention in wood-planing or woodworking machines has especialreference to machines of the class wherein are provided both upper andunder cutters, and particularly where an upper cutter is arranged as thefirst cutter of the machine and in advance of the lowercutter. Inmachines of this type it is necessary to provide in advance of the undercutter a Work-support or platen, which shall be arranged below the topof said under cutter a distance equivalent to the desired depth of cut,and in addition thereto a second platen or support back or in the rearof said cutter, placed on the level of the top of said cutter to receivethe work as it issues from the cutter. It is frequently desirable tovary the depth of cut of the upper or lower cutter or cylinder withoutvarying the finished thickness of the stock 0 for example, some stockmay be rougher at one side of the stock than at the opposite side,making it necessary to increase the depth of cut at one side andcorrespondingly lessen the depth of cut at the opposite side without 3 5varying the finished thicknessbut this can only be done, first, byvarying the level of the platen or bar, together with the entire bed ofthe machine, including the feeding-in rollers at the front of andrelatively to the first under cutter, or, second, by varying the levelof the cutter, together with the platen or bed and rollers, beyond andto the rear of the cutter. In machines as heretofore constructed,however, neither of these means is 5 possible, because the partsreferred to as a whole are built into'the machine and must remain alwaysin the same fixed relative or adjusted position.

One of the objects of our invention is to provide means by which therelative depths 5c of cut at the opposite side of. the stock may bevaried without changing the finished thickness of the stock.

In the preferred embodiment of our invention we accomplish this bymounting upon the main or bed frame of the machine a supplemental frameor member carrying the feeding-in rollers and the platen, bar, orworksupport, which precede the under cutter and form the bed orwork-support forand beneath the first top cutter and also providesuitable means,preferably an inclined plane or planes, for convenientlyvarying the level of this supplemental frame or member to thereby varythe level at which the stock shall apo5 proach the upper and undercutters, and thereby vary the relative depths of cut at opposite sidesofthe stock without varying the distance between the cutters and thecorrespon ding finished thickness of the stock.

Ourinvention further comprehends a novel construction ofplaning-machines in general.

Prior to our invention it has been customary in machines of this classto provide a massive bed-frame, usually composed of heavy side framesconnected by suitable cross members, and in these side frames are formedsuitable recesses or pockets for the under cutters, under feed-rollers,&c., the upper or cooperating parts being adjustably' mounted uponstandards erected upon this main or bed frame. This bed-frame is somassive that it is impracticable to place it in any particular machinecapable of properly finishing the several pockets or recesses for theparts referred to, it being necessary to finish said pockets or recessesby the much more laborious and costly handwork. To overcome thisdifficulty and to more conveniently construct a machine, as well as toreduce the cost of construction, my present invention comprehendsemploying a main or bed' frame substantially such as heretoforeemployed; but instead of forming the pockets or recesses for the variousunder cutters, rollers, and 9 5 other parts working from beneath,together with the bed, platens, or other forms of worksupport, in and asa part of this bed-frame,

as heretofore, our present invention comprehends providing a pluralityof superimposed supplemental frames adapted to be arranged, preferably,end to end and one close to another upon the main or bed frame, theunder cutters, under feed-rollers, bed or platen, and the like beingarranged upon these supplemental frames. The advantage of this novelconstruction is that each of these small supplemental bed-frames, withits plurality of parts adapted to operate from above and below upon thestock--such, for instance, as the upper and under cooperatingfeed-rollers, a cutter and its opposing work support or platen, and thelikemay be completely and independently finished by the use of improvedmachinery and completely set up, with its working parts in operativerelation one to another, in the several departments of the shop, wherethe same can be most conveniently and economically produced. Theseseveral supplemental frames each carrying their respective working orcooperative working parts of the machine are then assembled upon themain or bed frame and bolted or otherwise suitably secured thereto, theseveral supplemental frames with their working parts and the main or bedframe cooperating to form a single unitary machine. A further advantageresulting from this construction is that a certain interchangeability ofparts is provided, which renders it possible to completely change thecharacter of the machine, for using the same bed-frame, and the size andtype of the several supplementary frames erected upon the main or bedframe, together with the working parts carried by said frames, may bevaried at will, and so change the character of the machine as toadapt itforentirely dif ferent types of work.

Other features of our invention will be hereinafter described, andparticularly point ed out in the claims.

In the drawings, Figure 1, in side elevation, partially broken away,illustrates a woodworking-machine containing one embodiment of ourinvention; Fig. 2, a top or plan view of one of the adjustable supplemental frames; Fig. 3, a side elevation of Fig. 2; and Figs. at and5 top and side views, respectively, of a sufficient portion of a machineillustrating a modification of a part of ourinvention. Fig. (3 is a topplan view of the machine. Fig. '7 is a central vertical longitudinalsection thereof, and Fig. 8 is a top plan view of the frame with thesupplemental frames removed.

Referring to the drawings illustrating one embodiment of our invention,A illustrates one of the side frames of a suitable main or bed frame ofsufficient size and suitable construction to sustain the working partsof the machine, said main or bed frame being preferably provided at itsupper edge with a continuous plane face a. Arranged upon this main orbed frame A are a plurality of what we denominate supplemental frames13,13, B and B, each adapted to fit perfectly upon the main or bed frameand with the latter form a suitable rigid construction capable ofwithstanding the severe usage to which a machine of this type issubjected.

The supplemental frame B is herein shown as provided at its under sidewith a plurality of inclined lugs or faces Z) b, (shown in dotted lines,Figs. 1 and 3,) which rest at its entrance end upon corresponding butopposite inclines a on the main or bed frame A and at its feeding-outend upon a suitable incline Z), formed in and as a part of thesupplemental frame B.

A suitable adjusting device, shown as a shaft 1), journaled in the mainor bed frame, provided at its outer end with a suitable hand-wheel b andthreaded at its inner end to engage the supplemental frame B, furnishesmeans for moving said supplemental frame longitudinally of the machineto thereby, through the inclined supports described, cause verticaladjustment of the said frame for varying the level of its several parts.This supplemental frame B is provided with suitable recesses or pockets5 for the reception of the bearings for the journals 0 of the underfeed-rollers 0, shown as two in number, the upper feed-rollers 0" beingjournaled in suitable bearings 0 adjustably mounted in usual manner uponstands 0", erected upon said supplemental frame 13. The usual weightedlever 0 (shown in dotted lines, Fig. 1) is herein fulcrumed at 0 upon abracket c ,(shown also in dotted lines,) depending from and carried bythis adjustable frame B, it being connected in suitable manner byconnections c and c with and to control the pressure of the upperfeed-rollers of the work passed beneath the same. The supplemental frameB also carries at its front end (see Fig. 2) a platen or work-support c,the same being preferably adjustably mounted upon the said frame B-as,for instance, by the bolts cl and slots 0" (shown in Fig. 2 to enablethe distance between the edge of said support and the under cutter to beincreased. This work-support or platen c is arranged beneath and isopposed to-'i. 0., adapted to act upon the stock in opposition to thefirst or preparatory upper cutter (1, shown as adjustably mounted insuitable manner inthc stands (1, erected upon the supplemental frame 13.

The stands (1 and preferably the carryingboxes for the cutter (Z carrythe inverted platen or work-support (P, which is arranged over andconstitutes a work-support in opposition to the under cutter e,journaled in suitable bearings in a box or frame 0, arranged upon themain or bed frame A in a recess or pocket formed between thesupplemental frame 13 at one side and the supplemental frame B at theopposite side, said supplemental frames thereby constituting sides ofthe pocket in which the box or frame 6, carrying said under cutter, maybe slid in and out at the side of the machine upon the dovetailed guideor plate e (shown in Fig. 1) upon the main or bed frame.

The spoutfto conduct away the shavings from the under cutter cl is shownas formed in two parts, one part (indicated in dotted lines) in theframe or box 6 and the other in the supplemental frame E the two partsregistering when the cutter is in working position, one part, however,sliding past the other when the cutter is drawn endwise out of the sideof the machine.

The supplemental frame 13 as herein shown, carries one or more sideheads 9 and also has suitable pockets or recesses g for the bearings,containing the journals g of the lower feeding-out roller 9 opposed towhich is the upper feeding-out roller g journaled in suitable bearingsgiadjustably mounted upon stands erected upon said supplemental frame 13the latter provided with a suitable platen or worksupport g to supportthe work adjacent the side heads. The second upper or finishing cutterhis shown as journaled in usual manner upon the stands h ofthe-supplemental frame B the latter also carrying the platen orwork-support 7L2, arranged beneath and in opposition to the said uppercutter 72,. The several upper and under cutters may be adjusted asheretofore to produce different finished thicknesses of stock, and whenit is desired to vary the relative depths of cut at opposite sides of'the stock without varying the finished thicknesses of the same thesupplemental framev B, herein carrying the parts described, may beraised or lowered by rotation of the hand-wheel b to vary the level atwhich the stock approaches the first upper and under cutters. If itapproaches at a higher level, the depth of cut at the upper side will beincreased relatively to the depth of cut at the under side, and, viceversa, if the level of said supplemental frame be lowered the depth ofcut at the under side of the stock will be increased relatively to thedepth of cut at the upper side of the stock, all, however, withoutVarying the finished thickness of the stock passed between said cutters.This variation in relative depths of cut is obtained without in any wisechanging the adjusted position of any of the cutters and without in anywise varying the what may be fixed and permanent adjustment of thecutters and work-support table or bars beyond the work-support for thefirst cutter, so that our invention provides for the simplest possibleconstruction for obtaining the desired end.

The main or driving shaft on is shown at the feeding-in end of themachine, it being driven in suitable manner and belted by open and crossbelts m and m to and to drive the upper and under cutters d and c, itbeing also belted to and to drive the feed-shaft n, journaled insuitable bearings in the main frame and provided with a pinion n,meshing with a larger wheel 173, also j ournaled in said frame andhaving its shaft provided in turn with a second pinion a (All shown indotted lines, Fig. 1.) The pinion n meshes with a toothed wheel 0%,journaled in suitable bearings in the supplemental frame 13, said wheeln through the medium of an intermediate wheel a, driving a similar wheela said wheels 77, and a being fast on the journals of the lowerfeeding-in rollers c, the upper feeding-in rollers being driven in usualmanner therefrom.

It will be noticed that the supplemental frame B when adjusted causesthe toothed wheel 11 to move relatively to its driving-pinion n in thedirection of a tangent to the pitchline of said driving-pinion, saidtangent being of course parallel with the inclined planes on which saidsupplemental frame is adjusted, so that a considerable range ofadjustment is provided for without complicating the driving mechanism.

The feed-rollers g and g may be driven in suitable and usualmanneiyherein by connecting a sprooket-wheel 0 on the shaft of thepinion n by a sprocket-chain o with a sprocket-wheel oijournaled insuitable bearings in the frame adjacent the feed-roller 9 saidsprocket-wheel being connected with a toothed gear 0 in mesh with anddriving a gear 0 fast on the roller-shaft g from which the upper rolleris driven in usual manner.

In. Figs. 4: and 5 we have shown a slightlymodified form of ourinvention, wherein the adj listing-shaft 0", provided with a han d-wheelr, passes laterally through the frame and is connected by beveled gearso with the longitudinal worm-shafts r provided, respect-ively, withworms in mesh with worm-wheels r on the vertically-arranged adjusting-shafts 0*, upon which the bearings for the lower feeding-inrollers rest, said shafts r at their lower ends being herein representedas threaded for engagement with the nuts r in cars of thework-supporting platen 0 which latter is mounted upon an incline, as inFigs. 1 and 2. Rotation of the hand-wheel r thus causes simultaneousvertical adjustment of the bearings for the feeding-in rollers and theplaten or work-support for the first upper cutter, as in theconstruction Figs. 1 to 3, inclusive; but we desire it to be understoodthat our invention is not necessarily limited to the simultaneousadjustment of these parts.

The term work support as employed herein and in the claims includes anysupport for the work to hold it in proper alinement or position againsta working device or cutter of the machine, whether said work support isinverted in, arranged above a cutter, or arranged beneath a cutter, orwhether it is in the form of a platen or otherwise.
